I also have the red sea fan with white polyps.... these will sometimes close for a couple days to shed their outer skin, this is how they get rid of algae and grow.

I am unsure what myso shrimp is however if you are feeding mysis I am afraid this is too large unless it is chopped finely into a powerhead which could foul your water.

I have a few different types of gorgs and seafans in my tank, it is running a skimmerless set up with waterchanges once a week. I feed live baby brine that I hatch every 3 days and algae clean the tank glass once a week. Since there is no skimmer the particles continiously flow through the system until they get filtered out by these animals and this is hopefully enough for them to eat.
